Political participation is at an all-time high this election season, and a record number of voters have already started to cast ballots -- a few even camped out in Ohio to be the first in line for early voting yesterday.

But roughly 1 in 4 Americans still aren't registered to vote, according to the most recent Census report. Now is the time -- voter registration deadlines are less than a week away in most states.

We're trying to help increase participation by making sure you have easy access to voting information. Google's Voter Info Map currently puts registration, absentee and early voting information in one place. (If you're on a phone, you can check out our mobile version at m.google.com/elections.)

We're working closely with state and local election officials, the Voting Information Project and the League of Women Voters to centralize official voting information. Stay tuned for more posts on the project and details on how you can help confirm your local polling place address.

Leonardo DiCaprio, will.i.am, Tobey Maguire, Forrest Whitaker and a few of their friends put together the first in a series of public service announcements to encourage young Americans to register to vote -- and they include a link to our Voter Info Map.

As the Internet plays a greater role in helping people participate in elections, we're excited to help out. And you can, too. Help make sure everyone is ready for election day by reminding your friends and family to register and vote.
